FRANCIS E. CRAWFORD, OF NEYV SHARON, IOYVA,

BUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 380,867, dated April 10, 1888.

Application filed July 26, 1887.

To all whom it may concern:

Be it known that I, FRANCIS E. CRAWFORD, of New Sharon, county of Mahaska, and State of Iowa, have invented certain new and useful Improvements in Butter-\Vo'rkers, of which the following is a full, clear, and eXact description, that will enable others to make and use the same, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in power butter-workers, the same consisting in certain novel features in the construction, combination, and arrangement of the several parts, as will be hereinafter set forth.

Figure 1 is a plan view of a butterworker embodying my improved features; Fig. 2, a vertical longitudinal section of the same in plane 2 2, Fig. 1; Fig. 3, a vertical transverse section in the plane 3 3, Fig. 2; Fig. 4, a transverse section of the butter working table, showing the hinged sides or leaves raised to a part of the table-bed looking at the under side.

Referring to the drawings, A A represent the two horizontal side pieces or guide'rails, A the cross-bars, and A the legs, which together form the supporting-frame of the structure. A portion of the upper inner part of the side pieces, A A, is cut away their entire length to provide a pathway, a, for the longitudinal movement of the table-bed B, and prevent alateral movement of the same. This table-bed rests upon the track or friction-rollers a, placed at intervals along the inner side of the guide-rails.

To the under side and longitudinal center of the table-bed is rigidly secured the rackbar a, (see Figs. 2 and 3,) which engages with the pinion a mounted on the driving-shaft B. On the outer projecting end of this shaft is mounted the usual system of pulleys, a a a", for automatically transmitting and reversing the motion, so as to impart a reciprocating movement to the table-bed and the working-table proper lying on top of the same.

The belts transmitting the required power and motion will pass through the arms I) I), attached to the shifting-bar 13*, an endwise movement of which, first in one direction and then the opposite, alternately transfers the belts from the tight to the loose pulley, there- Serial No. 245.312. (No made-l.)

by causing the butter-working table to havea reciprocating motion. The shifting-bar B is placed in a transverse position below the ta ble-bed, the ends being loosely supported in the bearing-brackets b", secured to the under side of the frame guide-rails A A. The post I) is inserted in the upper side of the bar B and is provided on the upper end with the friction-roller b, as shown in Fig. 5, and indicated in dotted lines in Fig. 1. The diagonal cleats I) b are rigidly secured to the under side of the table-bed and are located near each end, as shown. Now as the traveling table reaches the fixed limit of its stroke these cleats alternately come in contact with the frictionroller mounted on the upper end of the post If, thus causing an endwise movement ofthe shifting-bar B, first in one direction and. then in the other, so as to shift the belts on the system of pulleys and automatically reverse the motion of the shaft B, and thereby cause the working-table to have a continuous reciprocating movement.

The inner end of the foot-lever O is secured in the supporting-frame, and extends therefrom to the front end of the machine and rests near the floor to bring the same within easy and convenient reach of the operators foot.

The operating end of this lever terminates in the elongated treadle-plate d, so that the foot-lever may be rocked in either direction, as may be required in stopping, starting, or reversing the reciprocating table. This footlever is connected to the shiftingbar B by the arm 0, so that the table may be reversed or stopped at any point in the line of travel independent of the automatic mechanism.

The working-table proper consists of the central and larger part, 0 permanently secured to the table-bed, and the side pieces or leaves, 0 0*, connected at each end to the central part, 0, by the hinged joints (1. The side leaves are not fastened to the table-bed, but are adapted to fold inward upon the central part, as shown in Fig. 4. The object of constructing the Working-table in three parts is to enable the operator to quickly heap up or mass the butter in the center of the table from the sides when flattened out by the action of the roller D, thus greatly facilitating the work, as the butter can be heaped up without stopping the machine and the use of a paddleisdispensed with. Thebutterisheaped from the ends of the table by a proper manipulation of the roller. The folding leaves are provided with handles (2. The channels d 5 serve to conduct the expressed liquid away.

The working-roller D is provided with suitable journal-bearings in the operating-levers D D arranged on each side of and extending lengthwise of the table. The inner ends of IO the levers D D are bent upward a little (see Fig. 2) and pivoted to the upper ends of the posts d d the lower ends of which are rigidly secured to the supporting-frame of the structure. This arrangement enables the roller to be conveniently raised and lowered or conveniently thrown up out of the way. The outer ends of the operating-levers D D are connected by the rounds d (F, which form handles. The overhead cord (1 serves to retain the levers and working-roller up out of the way when necessary.

The rotating roller D, for expressing the liquid matter from the butter, occupies a fixed position relative to a horizontal movement, but is vertically adj nstable by the raising and lowering of the levers D D in which said roller has fixed journal-bearings. By this arrangement the position of the roller is changed by the simple movementof the working-levers and without having to adjust the journal-bearings.

A light or heavy pressure can be maintained on the surface of the butter, as may be required, and the whole operation of the machine easily and conveniently controlled, thus greatly facilitating and shortening the process. 3 5

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

I. In a butter-worker,the combination,with a reciprocating table carried by a table bed, said table consisting of the central part, Ofland the side leaves, 0 O, hinged to and adapted to be folded over on said central part, as de scribed, of the hand-1evers D D, pivoted independently of the table-bed, and the roller D, having fixed journal-bearings in said levers, whereby said roller may be instantly raised upward to permit of the table-leaves being turned inward to mass the butter on the central part of the table without stopping the machine, substantially as set forth.

2. In a butter-Worker, the combination,with a reci proeatin g table, of the roller D, the handlevers D D", bent upward at their inner ends, and the posts d d to which said bent-up ends 5 are pivoted, substantially as set forth.
